R kriging output not generated

QGIS version | 2.18.13 | QGIS code branch | Release 2.18

I'm getting an error running the Kriging Rscript

It ends with this - and I get no output graphs or layers. I have also tried saving files instead of temporary outputs and get no different result. I have run in R - loading point file (rgdal::readOGR) and specifying field, and it works there. How can I help to resolve this?
